# Using 3-5 Singapore Math materials to understand the Common Core State Standards in Mathematics

Goal: To increase teachers’ understanding of the content in the Common Core State Standards in Mathematics with the focus on the big ideas in each grade.

Specific topics include:

Emphasis on the key ideas in each semester and each grade level. The “how” of the Singapore Math textbooks, workbooks and teachers‘ guides in teaching Common Core State Standards in Mathematics.
